Is it possible to build lwIP libraries for UDP support alone? Yes. You have to create a lwipopts.h file which contains options to enable/disable (see opt.h to know existing options). You can file some informations on : http://lwip.scribblewiki.com/LwIP_Main_Page (not yet complete, but, a good start) https://savannah.nongnu.org/projects/lwip/ https://savannah.nongnu.org/task/?7068#comment2 <https://savannah.nongnu.org/task/?7068> (some links) ==================================== Frédéric BERNON HYMATOM SA Chef de projet informatique Microsoft Certified Professional Tél. : +33 (0)4-67-87-61-10 Fax. : +33 (0)4-67-70-85-44 Email : [EMAIL PROTECTED] Web Site : http://www.hymatom.fr <http://www.hymatom.fr/> ==================================== P Avant d'imprimer, penser à l'environnement -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] De la part de Rohit Arul Raj Envoyé : mardi 14 août 2007 09:21 À : [email protected] Objet : [lwip-users] Building lwIP libraries - general info Hi all, I am a newbie to lwip. I have an embedded target board running which does not have any OS support. I need to implement UDP stack on this board. 1. Is it possible to use lwip libraries for this? 2. Where should i look for target dependencies in lwip libraries? Any documentation on this? 3. Any standard procedure to be followed to build lwIP libraries? i couldn't see any standard makefiles or configure scripts. 4. Is it possible to build lwIP libraries for UDP support alone? Any help will be very much useful. Regards, Rohit
